"Professional and experienced lead generation company with very personable team members"

What do you like best about Callbox?

Very good responsiveness on email from the team, especially Hera. This meant we could always get a quick answer to a problem, even outside local office hours. Plentiful and useful feedback on the weekly huddles with plans for improvements.

The editing of email templates was a lengthy process as many changes requested were not made the first time , so it took longer than necessary to get marketing materials approved.

"Great partnership for all things digital marketing"

What do you like best about WebFX?

By partnering with WebFX on our digital marketing and SEO, we've gotten more time back to focus on our business operations and client relationships. As a small team, we don't have the in-house expertise to focus on SEO, so we knew we wanted to outsource to a trusted partner. We are very happy with our decision to partner with WebFX.

What do you dislike about WebFX?

The only downside that comes to mind is the time it takes to see growth in organic SEO, which isn't due to WebFX, but due to search engine rules. WebFX has helped us develop a strategy to grow our online presence and I'm excited to continue to see those results as more time passes.
